Leidos is seeking a Research Scientist / Engineer for our NETL Pittsburgh, PA Site. The Research Scientist / Engineer will conduct research and development of cladding materials for sapphire optical fibers. These claddings are to be used in distributed temperature sensing in energy-related applications such as boiler exhaust, heat recovery steam generators, gas turbines, and solid oxide fuel cells.

Primary Responsibilities:

Apply MgAl2O4 and other potential claddings using a sol-gel process

Test the mechanical durability of claddings, including resistance to abrasion and spalling when flexed. Mechanical testing initially will include bending the fiber and observing delamination or cracking.

Test the resistance to chemical damage and contamination in various gas atmospheres.

Measure the optical performance of the cladding before and after exposures and mechanical testing.

Investigate the performance of other materials identified through the literature reviews.

Develop reel-to-reel fiber coating and manufacturing facilities for the most promising cladding candidates

Demonstrate cladding stability under application relevant conditions.

Scale up the coating process for MgAl2O4 while further exploring alternative processes for higher temperature operation including, but not limited to, porous Al2O3.

Scale up the coating process for porous Al2O3 or an alternative cladding material for higher temperatures greater than 1000oC

The candidate will provide general R&D support to NETL-LRST Advanced Sensors staff. The candidate will participate in-group meetings to discuss current research and promote discussion with fellow researchers.

Preference for experience in a national laboratory environment or R&D industrial lab where safe working practices are paramount.

Familiarity with vacuum compliant systems is a plus

Position may require travel. Position may require the ability to pass and maintain a Security Clearance.
